Yes it is.

I've asked for it, but finding people to review code is hard, as you
know.  It's only 13k lines long, smaller than a serial port driver (my
unit of code review), so it's not all that big.

It's smaller than the USB3 host controller driver as well, and very few
people ever reviewed that beast :)

If you know of a way to force others to review code, please let me know.
